Using HTTP/2 with ARR and IIS 10
This article has been moved to its new home here: https://benperk.github.io/msdn/2016/2016-01-using-http2-with-arr-and-iis-10.html
I was asked a question about if the Application Request Router supports the HTTP 2 protocol on IIS 10 (not sure what it will be called). I was pretty confident that it did, but nothing beats a test to confirm it. So that is what I did. I used this article here that contains some good information about HTTP/2 on IIS 10. As I read through the instructions, the only requirement for using the HTTP/2 protocol is that the request is made over HTTPS. And of course, you need IIS 10…
I found no difference in the setup of ARR on IIS 10, so this article here still seems to apply. I prefer using the Web Platform Installer for adding IIS modules, but there are numerous techniques.

To test and confirm that the HTTP/2 protocol is used, I access the ARR server using Microsoft Edge on Windows 10 and captured the Network trace using the F12 Developer Tools. As you can see in Figure 3, HTTP/2 is shown in the Protocol column and thus supports my initial claim that ARR works with HTTP/2 on IIS 10.
